REGISTER 17-3:
The analog reference voltage is software selectable to
either the device’s positive and negative supply
RA3/AN3/V
The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode. To oper-
ate in SLEEP, the A/D conversion clock must be
derived from the A/D’s internal RC oscillator.
The output of the sample and hold is the input into the
converter, which generates the result via successive
approximation.
A device RESET forces all registers to their RESET
state. This forces the A/D module to be turned off and
any conversion is aborted.

Each port pin associated with the A/D converter can
be configured as an analog input (RA3 can also be a
voltage reference), or as a digital I/O.
The ADRESH and ADRESL registers contain the
result of the A/D conversion. When the A/D conver-
sion is complete, the result is loaded into the
ADRESH/ADRESL registers, the GO/DONE bit
(ADCON0 register) is cleared, and A/D interrupt flag
bit ADIF is set. The block diagram of the A/D module
is shown in Figure 17-1.
